Okay, so here's the prob. As some of you know (or not!), I had a heap of keyhole cichlids - first time successfully bred. All the other fish were removed from the tank, making it a species tank, and a great looking one too. ANYWAY, managed to get rid of all but 10 of the babies and decided to reintroduce the other fish to the tank. As far as I know, I went about it the right way.
I removed the parent keyholes, putting them in their own tank for 2 hours. I also planted some new plants in the aqaurium and changed around the look of everything. Then, I put the other fish in (pleco, rosy-barbs, cherry barb) and after waiting what seemed an age, put the parents back in. Everything was well, for a while.....
All the smaller fish were having a great time playing in the current and checking out the new 'surroundings' but once the parents adjusted again, they just went nasty.(The parents) I (somehow) managed to remove the male keyhole and put him in a tank of his own but within 18 hours, he was on his side and fighting for life. (I wasn't here at the time, but was told.) The female at this stage, had calmed down and was almost kind to the other fish. Once the male was put BACK in the main tank and came right, both parents were again acting aggressively. They are even picking on their own babies.
Soooooo, my question is "Now what?". Do I, um, what? There is no chance of putting the adults in a separate tank, as the next size I have is only a 28L. Does anyone know of a way to stop this pair from being nasty or am I being ridiculous to think so? Would they be ready for another breed? Do I get rid of them? Do I send them to the fish afterlife for the sake of my other fish? HELP!
(Okay, it's been a bit of a rant, but geez! These fish are beautiful but I don't won't to risk the rest of the tank, including the lovely siamese fighter being ripped to shreds.) Any advice is HIGHLY invited! ! ! !
